Icy is right though, grim/soul skill immune characters can, under certain conditions, be stripped of their immunity, and moving the field is the currently only known case of this, because it would mess up the field.See here and here.

It is, in Logress' words, unavoidable that she gets moved, but she shouldn't engage. (It's also "Engage all units of Lv4 and higher")

Your reply at the end was hilarious, big lol moment for me Yeah the wording on the cards are sometimes blurry, but it wouldn't make sense to add in too much details into it.How about stating the exceptions in the detailed play rule section?
